OptiSense

Inspiration

The driving force behind OptiSense is rooted in the pressing healthcare challenges faced in Africa, particularly concerning Diabetic retinopathy (DR) diagnosis. With an escalating prevalence of diabetes in the region, currently projected to increase from 19.4 million in 2019 to 47.1 million by 2045, the need for accessible and accurate DR diagnostics is more critical than ever.

The limitations of traditional diagnostic systems in Africa, marked by a scarcity of ophthalmologists, insufficient training, and a lack of systematic screening programs, underscore the urgency of innovative solutions. OptiSense draws inspiration from this need, envisioning a transformative impact by harnessing the power of artificial intelligence to revolutionize DR diagnosis.

The commitment to addressing these challenges, particularly in regions with limited healthcare infrastructure, has fueled the development of OptiSense. By embracing the power of AI, this initiative aspires to provide standardized assessments, enhance accessibility in underserved areas, streamline diagnostic processes, and ultimately contribute to early detection and intervention, potentially averting avoidable blindness caused by diabetic retinopathy. Through innovation, compassion, and efficacy, OptiSense aims to redefine the landscape of diabetic retinopathy diagnosis in Africa.

How we built it

Building an Effective Diabetic Retinopathy Prediction Model using ResNet Input Layer: The input layer expects images of size 224x224 pixels with 3 channels (RGB).

ResNet50 Base Model: The base model is ResNet50, a deep convolutional neural network with 50 layers. It has been pre-trained on the large-scale ImageNet dataset, which enables it to extract meaningful features from images.

Global Average Pooling Layer: The output of the base model is passed through a global average pooling layer. This layer reduces the spatial dimensions of the features to a fixed size, resulting in a 1D feature vector for each image.

Dense Layer: A dense layer with 256 units and ReLU activation is added on top of the global average pooling layer. This layer introduces non-linearity and enables the model to learn more complex representations.

Final Dense Layer: The last layer is a dense layer with the number of units equal to the number of classes (5 in this case). It uses the softmax activation function, which produces class probabilities for each input image. The model predicts the class with the highest probability as the final prediction.
